A customer has a Britannia range cooker which trips the RCD everytime the main oven is switched on. At first the problem was intermittent and progressively worsened until now it happens every time the oven is switched on. The RCD trips even with the oven temperature setting on minimum before the audible click of the thermostat, so even before a signal is sent to the heating elements the RCD is tripped. I'm inclined to think that the switch is at fault as the RCD trips when the top or bottom oven element is switched on. Should I move it to a non RCD side as it is on a 40A MCB? There is no socket next to the isolation switch so RCD isn't an issue. Any advice is most welcome.
